Hi, i have a honda accord 2007. I had the car go for a diagnosis and its come up with faulty ‘o2 sensor"?? Would anyone know if thats the pre-cat or post-cat?
there’s no way to tell without the OBD-II code. If you don’t have it, your best bet is to go to an AutoZone or other auto mechanic and get them to run the diagnostic. They can give you the printout so that you can either purchase the specific parts from them online or elsewhere.
